A Malaysian airline reportedly with 295 people on board has crashed in Ukraine near the Russian border, on a flight from Amsterdam to Kuala Lumpur.
Malaysia Airlines said it had lost contact with Flight MH17 from Amsterdam. The last known position was over Ukraine, it said in a Tweet.
Separatist rebels have been fighting government forces in the region.
A number of Ukrainian military planes have been shot down by missiles in recent weeks, with Ukraine accusing Russia’s military of supplying advanced missiles to the rebels.
Earlier on Thursday, Ukrainian officials accused the Russian air force of shooting down one of its ground attack jets on Wednesday.
Anton Herashchenko, an adviser to Ukraine’s interior minister, was quoted by the Associated Press as saying the plane had been hit by a missile at an altitude of 10,000m (33,000ft). The claim could not be verified independently.
The source which spoke to Reuters said the plane had failed to enter Russian airspace.
The UK Foreign Office said it was aware of the reports of the crash and was “urgently working to establish what has happened”.
Recall that a Malaysian airline disappeared earlier this year carrying almost the same number of passengers and until date the flight has not been found.
